"I can't have the kind of passionate sex with my husband anymore," says Aya Kasuga Aya, 40. She is a full-time housewife who has been married for 16 years this year and has a son and a daughter with her husband, leading a smooth-sailing family life. However, before she got married, Aya's hobby was traveling alone, like a backpacker. After getting married, she became a full-time family man and got used to a settled life. "When I was young, I was fearless, so I would have a one-off relationship with a man I met. Every day was exciting." As the years went by, the sex with her husband became monotonous, and she started to remember the past. Today, while her husband was away on a business trip, she took advantage of the opportunity to have her first adulterous sex. Her lewd body, which gets wet just from a kiss, shows off her intense eroticism.
